Clustering tomcats

[Prakash Dwivedi]

hello Friends,
I have to develop an architecture where there is a cluster of tomcats 4.1.8(around 5) and an apache 2.0.4 server. What i have to do is that apache should listen to all the http request and transfer the request to any tomcat doing loadbalancing. Any suggestions how should i do. Also is there some way so that i can increase the efficieancy of the system.
thanx in advance

Hi Prakash,
I would point you to Tangosol's Coherence in-memory clustered caching product. We have developed an HTTP-Session Replication Module for Tomcat which replicates the session data in-memory across all of the cluster nodes. This approach allows for the use of non-sticky loadbalancing and pure failover (since each cluster node has all the session information).
Later.
